4 If in the "∞" MΩ end exceeds the limit of the peak charge state , transient short-circuit voltage capacitor with a screwdriver poles , you can see there are sparks and hear the "pop " and look discharge sound. If the digital voltmeter also received a shake table can be found just around fast shake , shake table can emit nearly l50v voltage.vPSservice manual download site

5 were detected by the shake table and shell insulated high voltage capacitor poles . Normal should be ∞. Note that this case requires a "fast multi- shaking ", so shake table issued by the voltage reaches the maximum value. If the charging and discharging of the results to reach the detection of the above requirements, it indicates the presence of high voltage capacitor leakage or open questions , use the shake table to detect high voltage capacitors, shaking table pointer by substantial deflection , high-voltage capacitors can be charged and discharged process is very intuitive and vividly " demo " came out , just shake fast lap , "Demo " process up to 15 seconds. In contrast with the pointer table detection voltage capacitor charging and discharging process generally only one second or so, but the pointer over the maximum swing angle 45 ° In addition , with the shake table to detect high voltage capacitor insulation , it is a pointer table unmatched.vPSservice manual download site
